This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
What is structural nonlinearity? The notion of linearity has become so ingrained in the practice of structural engineering that the term nonlinearity feels shadowy and ominous, vague and unconventional. Nonlinearity means that the structural behavior will be different, but how? What constitutes nonlinearity and what are the different types?
There are multiple components, conditions, and behavior that all fit under the umbrella of structural nonlinearity. The terminology surrounding nonlinearity can be overwhelming – P-delta, secondary effects, inelastic behavior, softening/hardening, large deflections, gap elements, sway moments, follower forces, nonprismatic, directionality, etc.
What are all the different types of nonlinearity that are possible in structural analysis? Why are they different and when do they need to be included? This course aims to introduce the full range of structural nonlinearity, describe their behavior and effects, and provide insight into when nonlinearities should be included in analyses.

Introduction to Structural Nonlinearity
The course was challenging. It woke up brains cells that have been asleep for a while. However, apparently some of the brain cells never did wake up. Fortunately I managed to pass the course. Enjoyed taking it. No number crunching, but thought provoking.
